Introduction Anti-virus software is the first line of defense against computer viruses that can spread very quickly using your Internet and/or local network connection, through e-mail attachments, network shares, peer-to-peer filesharing, IRC chat file downloads and browsing infected web sites. An infected computer could cause your system to malfunction, limiting your productivity. Virus infections could cause loss of valuable data or even more embarrassing – distribution of confidential or personal data. Virus infections can require a lot of man-hours to clean up or rebuild your system. Often when one computer gets infected, it also affects other computers in your office and on your network. The best way to protect your system from viruses is to update your anti-virus program daily and scan your hard drive for viruses weekly. Information Technology Services (ITS) has a site license of McAfee VirusScan anti-virus software that active University of Hawai‘i (UH) faculty, staff and students may use at no extra charge on their Windows computers. McAfee VirusScan Enterprise is licensed for use on UH owned computers (desktops and laptops), including computer labs on campus, and home computers (one license only) for active UH faculty, staff and students. (See “System Requirements” for supported operating systems). Active UH faculty, staff and students include any student taking a UH credit course and any faculty/staff currently employed by UH. UH faculty, staff and students, upon termination of employment or student status at UH, must uninstall all site license copies of McAfee VirusScan and VirusScan Enterprise, per our site license agreement with McAfee.

ITS provides in-depth technical support for McAfee VirusScan and limited support for other anti-virus products. Make sure that you have only one anti-virus product installed, that your virus definitions (DAT files) are kept current and your anti-virus software is configured properly. This document covers the basics of installing, configuring and using McAfee VirusScan Enterprise 8.5i. Product Overview McAfee VirusScan Enterprise (VSE) protects Windows desktops and file servers against viruses, Trojans, worms, potentially unwanted code and programs. VSE is licensed for use on UH owned computers and home computers (one license only) for active UH faculty, staff and students. It supports Windows 2000, Windows XP, Windows Vista and Windows server 2003. It also supports 64-bit Windows. New or improved features:

• Support for 64-bit operating systems o Buffer overflow protection and scanning of Lotus Notes databases are not supported on

64-bit operating systems. • Quarantine Manager Policy

o Before the on-access or on-demand scanner cleans or deletes a file, a backup copy of the original file and its registry value is made in the quarantine directory. The quarantined items can be automatically deleted after a specified number of days or selectively deleted or restored.

• 5100 series scan engine o Incremental scan engine updates o Two versions of the scan engine, 32-bit and 64-bit o Ability to use different sets of detection definition files (DAT) at the same time,

providing for faster and more efficient scanning. • Detection of rootkits in memory • Enhanced access protection

o Standard protection level allows installation and execution of legitimate software. o Maximum protection level protects most critical settings and files from being modified.

Microsoft Windows Vista (excerpt from VirusScan Enterprise 8.5i readme) 1. Before remotely connecting to a computer with the Windows Vista operating system, you must complete these steps: a. From the computer with the Windows Vista operating system, modify the Windows Firewall settings to allow "Remote Service Management" as follows: - From the "Start" menu, select "Control Panel | Security | Windows Firewall | Change settings" - On the "User Account Control" dialog box, click "Continue." - On the "Exception" tab, select "Remote Service Management" on the "Program or port" list.

Page 3: McAfee VirusScan Enterprise 8 · ITS provides in-depth technical support for McAfee VirusScan and limited support for other anti-virus products. Make sure that you have only one anti-virus

McAfee VirusScan Enterprise 8.5i WIN1037 Page 3

b. Start the "Remote Registry" service on the target computer with the Microsoft Windows Vista operating system, before remotely connecting to it. To start the "Remote Registry" service: - From the "Start" menu, select "Control Panel | Administrative Tools | Services. - If the "User Account Control" dialog box is available, click "Continue." - Ensure the status of the "Remote Registry" service is "Started." If necessary, start the service. We recommend that you stop the "Remote Registry" service on Windows Vista after completing the remote configuration. 2. When using the "Browse" option to connect to a remote console with the Windows Vista operating system, the list of computers does not display for a long period of time or at all. If the list does appear, you can select a computer, but the "OK" button is disabled so the connection cannot be made. You can make a remote connection to the console of other computers by specifying the full computer name or the IP address of the computer to which you want to remotely connect. 3. When running update or mirror tasks from the VirusScan Console on a system using Windows Vista, the task progress dialog box does not display while the task is running. However, the task completes successfully. You can view information about the task in the activity log. 4. When a connection is blocked in a share folder on a computer with the Windows Vista operating system, the blocked connection cannot be unblocked using the "Unblock All Connections Now" button in the On-Access Scan Statistics dialog box. The "Unblock All Connections Now" button is disabled in this scenario. The blocked connection will be unblocked after the default time out. 5. Buffer Overflow Protection is not supported on Microsoft Windows Vista operating systems.

Before On-access or On-demand scanners in VirusScan Enterprise clean or delete a file, it makes a backup copy of the original file in the quarantine folder. The default quarantine folder is c:\quarantine. The default policy is to automatically delete quarantined data after 28 days. You may modify the policy to your liking.

In the Manager tab, you can manage (restore, check for false positive, rescan, delete) quarantined data. Right click on the quarantined entry and select the desired option. Click Apply and OK.

I Found a Virus, Now What? When VirusScan Enterprise detects a virus, you will receive a warning similar to the following:

Note: eicar is not a true virus. Upon detection, VSE on-access scanner made a backup of the original file in the quarantine folder (c:\quarantine). Then VSE tried to clean the virus but couldn’t so the infected file was deleted.

For help with virus clean up, we need to know the name of the virus.

Please write down the name of the virus detection.

Both on-access scanner and on-demand scanner are configured to attempt cleaning the file first; if that fails, the file will be deleted. If you discover that VirusScan deleted a legitimate file by mistake, go to Quarantine Manager to restore it from the quarantine folder. Here is another example of a virus detection when the user attempted to save an email attachment infected with the W32/SirCam@MM virus.

McAfee VirusScan Enterprise 8.5i WIN1037 Page 25

In this case, it is known that W32/SirCam@MM is a virus and the infected file can be deleted. Open Quarantine Manager and delete the infected file from the quarantine folder. Sometimes when the virus is newly introduced, VirusScan may only be able to detect the virus but may not be able to clean it. In those cases, you should delete the infected file and restore the original file from a clean (pre-infected) backup or original media. Once the virus is disinfected, a report will be given depending on the status of the virus and whether the virus could be cleaned, deleted or renamed. The log files, OnDemandScanLog.txt and OnAccessScanLog.txt, are saved in the C:\Documents and Settings\All Users\Application Data\Network Associates\VirusScan folder. Once you have disinfected the virus (or deleted the infected file and restored it from backup) and emptied your Recycle Bin, rerun VirusScan with the scan all files option once more to ensure that your system is clean.

Troubleshooting Q: While checking for an update for VirusScan, I get this message: "Error occurred while

downloading file SiteStat.xml." What does that error mean? A: It usually means that there is a problem connecting to the repository (server) for DAT updates.

Some possible items to check:

1. Is your network connection working properly? Can you get to other sites via a web browser? (If yes, your network connection is ok.) If on the campus wireless, are you properly logged in to the wireless network?

If you detect a virus and need assistance cleaning or removing it, please contact the ITS Help Desk at 956-8883 with the name of the virus, your version of VirusScan, the date of your virus definition, and the version of your scan engine.

2. Do you have a personal firewall that might be blocking access to the server? (If you disabled your personal firewall program, are you then able to update your DAT files?)

3. It might be due to many people accessing the server and trying to update their files at the same time. Try again in 15 minutes.

Q: After installing VSE 8.5i, one of my programs stopped working properly. What should I do? A: There may be a conflict with VSE 8.5i’s buffer overflow protection. To disable buffer overflow

protection, open VirusScan Console. Double click on Buffer Overflow Protection, clear Show the messages dialog box when a buffer overflow is detected then clear Enable buffer overflow protection. Please clear the check boxes in this order. Click Apply and OK. Buffer Overflow Protection should be Disabled in VirusScan Console. If this does not resolve your problem, contact the ITS Help Desk at 956-8883 or email [email protected].

Q: I've noticed McAfee VirusScan is not autoupdating. I am running MS Windows XP SP2. How do

I fix this? A: Please check to see if you are running the Windows XP SP2 firewall. To disable the firewall:

1. Click Start. 2. Click on Control Panel. 3. Double-click on Security Center. 4. Click on the Windows Firewall link. 5. Check Off. 6. Click OK.

Q: I got error message: "Failed to initiate Common Updater subsystem. Make sure the McAfee

Framework Services is running. McAfee Common Framework returned error fffff95b@2" after I clicked on Update Now from the vshield system tray icon. I had just installed VirusScan Enterprise 8.5i and restarted Windows. What does this mean?

A: VirusScan Enterprise 8.5i may take awhile to load completely during startup. Open VirusScan

Console and ensure that the Autoupdate task is listed. If the Autoupdate task is not listed, please wait until it appears. If Autoupdate task is listed, run Update Now from the vshield system tray icon or right click Autoupdate in VirusScan Console and click Start.
